Gastric inverted polyp successfully resected by underwater endoscopic mucosal resection.
Article in DEN open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A 47-year-old man, who underwent an annual esophagogastroduodenoscopy as part of his routine check-up, was found to have a small subepithelial lesion on the posterior wall of the gastric body in 2013. The lesion gradually increased in size during follow-up. In 2024, 11 years after the initial detection, the lesion had grown to over 10 mm in diameter and exhibited central erythematous depression. Endoscopic ultrasonography was performed, revealing that the lesion originated from the second layer with uniformly low internal echogenicity. A biopsy suggested the possibility of a benign stromal tumor, but a definitive diagnosis was not achieved. To obtain a complete biopsy, en bloc resection was performed using underwater endoscopic mucosal resection. Histopathological examination confirmed the diagnosis of a gastric inverted polyp. Since gastric inverted polyps with central depression or erosion have the potential for malignancy, endoscopic resection is recommended.
